scalatest selenium 示例编译错误

Question

我是 scala 的新手，但非常想将 ScalaTest 与 Selenium 一起使用。我直接从http://www.scalatest.org/user_guide/using_selenium 复制并粘贴了示例。但在下面的语句中出现错误

"The blog app home page" should "have the correct title" in {
    go to (host + "index.html")
    pageTitle should be ("Awesome Blog")
}

错误出现在“{”之前的“in”关键字上，它表示：

此行有多个标记 - 发现隐式转换：“博客应用主页”应该“具有正确的标题”=> convertToInAndIgnoreMethods("博客应用主页"应该"有正确的标题") - 使用替代方法重载方法值：(testFun: BlogSpec.this.FixtureParam => Any)Unit (testFun: () => Any)Unit 不能应用于 (Unit) - 使用替代方法重载方法值：(testFun: BlogSpec.this.FixtureParam => Any)Unit (testFun: () => Any)Unit 不能应用于 (Unit) - 发现隐式转换：“博客应用主页”=> convertToStringShouldWrapper("The 博客应用主页”）

我相信我通过 maven 选择了所有正确的版本：

<dependency>
  <groupId>org.scala-lang</groupId>
  <artifactId>scala-library</artifactId>
  <version>2.10.2</version>
</dependency>

          </args>
        </configuration>
      </execution>
    </executions>
  </plugin>

尝试了很多来解决这个问题，但失败了。任何帮助将非常感激。也尝试过https://bitbucket.org/olimination/hello-scalajava.git，但由于 maven 错误而无法运行。

这个问题似乎是一个很老的问题，也许你已经设法解决了，但是这个示例是为我编译的。

我认为问题出在import 语句中，例如 IntelliJ Idea 似乎提出了错误的语句，使用import org.scalatest._ 时似乎一切正常，否则我会得到你的编译错误。

这是完整的来源：

import org.openqa.selenium.WebDriver
import org.openqa.selenium.htmlunit.HtmlUnitDriver
import org.scalatest.selenium.WebBrowser

import org.scalatest._

class BlogSpec extends FlatSpec with ShouldMatchers with WebBrowser {

    implicit val webDriver : WebDriver = new HtmlUnitDriver

    val host = "http://localhost:9000/"

    "The blog app home page" should "have the correct title" in {
        go to (host + "index.html")
        pageTitle should be("Awesome Blog")
    }
}

我建议使用最新版本的框架和插件（如果可以的话，也可以使用 Scala，我还是保留 2.10），这是我的pom.xml：
